3 Claims.

This invention relates to dies and methods of cutting fourchettes.

Conventional fourchettes, as implied by the name, are forked or horseshoe-shaped, being folded longitudinally near their middle portions when assembled in gloves to space the palm and back sides of the fingers. The crotches between the fingers are conventionally completed with quirks, darts or like small diamond-shaped pieces inserted at the folds of the fourchettes.

Fourchettes have heretofore been made by stamping leather placed on a cutting block, the stamped out fourchettes being picked up manually. In the case of fitted fourchettes, the same die can be used for the two fourchettes forming the inner sides of the third and fourth fingers in paired gloves, if the leather is turned over between the stamping, for these two fourchettes are shaped as mirror images of each other, being identical as to form and size except for the fact that left and right are reversed. One other die can be used to stamp the four fourchettes forming the facing inner sides of first, second and third fingers in a pair of gloves. The two fourchettes forming the opposed inner sides of the second finger in one glove form mirror images of each other. The fo-urchette forming the facing inner sides of the first and second fingers in one glove is identical with the fourchette forming the facing inner sides of the second and third fingers of the other paired glove, and the same relation obtains for the fourchette forming the facing inner sides of the second a d third fingers in the first glove and the fourchette forming the facing inner sides of the first and second fingers of the second glove. Since the four fourchettes for the first, second and third fingers of a pair of gloves consist of two pairs of identical fourchettes, each pair forming a mirror image of the other, only two reversals of the leather are required in cutting the same.

The present invention provides fourchettes that are straight rather than fOrked or horse-shoe shaped. These fourchettes comprise an intermediate longitudinal edge portion that is quirked, i. e. characterized by a reentrant angle that is spaced from the opposed edge by a distance greater than a seam. The fourchettes, when assembled in a glove, are folded transversely back on themselves at the point' of the reentrant angle, a quirk being combined therewith. Such fourchettes may be stamped or cut contiguously side by side in close parallelism.

This invention further provides double dies that cut in a single stroke a pair of fourchettes 55 of related as mirror images and hereinafter referred to as right and left fourchettes. Such dies are particularly adapted for cutting the straight fourchettes of this invention. The dies may have t insides of their cutting edges chamfered to fiex and pick up the stamped-out fourchettes therebetween. Pins or other means may also be rovided for assisting in picking up stamped-out fourchettes. Picked-up fourchettes may be removed by an ejector disposed between the cutting blades.

The fourchettes of this invention are related to each other in form and shape as the conventienal fourchettes referred to hereinabove, two dies being required for stamping the fourchettes for one pair of gloves. When fourchettes are stamped with the dies of the present invention, no reversing of the leather need be made, the number of cutting operations is reduced, and manual picking up of each stamped-out fourchette is eliminated.

It is therefore an important object of the present invention to simplify and expedite the stamping of fitted fourchettes by eliminating the need for reversing the leather in cutting mated right and left fourchettes and by reducing the number of cutting operations and picking-up steps.

A more specific object of the invention is to provide fourchette stamping dies and methods for cutting, in a single stroke, mated right and 1e t fourchettes.

Another specific object of the invention is to provide fourchette stamping dies capable of picking up stamped-out fourchettes.

Still another specific object of the-invention is to provide, in dies capable of picking up stampedout fourchettes, means for ejecting an accumulation of stamped-out fourchettes.

A further obieet of the invention is to provide dies for stamping mated right and left straight fourchettes simultaneously and contiguously.

Other and further objects of the present invention will become apparent to those skilled in the art from the following description and appended drawings.

This invention (in preferred forms) is illus trated in the drawings and hereinafter more fully described.

Figure 10 shows a transverse cross-sectional view of another double die for stamping straight fourchettes according to this invention provided with pins for assisting in picking up stamped-out fourchettes.

Figure 11 shows a top plan view of a pair of right and left straight fourchettes as stamped with the die of Figure 10 having intermediate longitudinal edge portions curved to outturned points.

Figure 12 shows a top plan view of mated right and left darted fourchettes stamped contiguously according to this invention.

As shown on the drawings:

In Figures 1 to 4, the reference numeral ID indicates generally a double straight quirked fourchette die according to this invention. The die comprises three spaced cutting blades I I extending in the same general direction and a plate I2 bridging the middle portion of the blades. A handle I3 extends upwardly from the plate I2.

As best shown in Figure 2, the three cutting blades II are made integrally, with the outer two blades having ends deflected inwardly and the central blade having forked ends that are united with the deflected ends of the outer blades to outline the tapering divergent ends of the fourchettes. The central blade divides and spreads apart nearly at its middle into diamond shape. The cutting blades so configured will stamp out the fourchette of Figure 8 and its mate.

As shown in somewhat exaggerated form in Figures 3 and 4, those sides of the cutting blades facing other cutting blades have their edges chamfered, as at I4. Figure 4 illustrates how fourchettes 30 such as those shown in Figure 8 stamped from a piece of leather I6 stretched over a cutting block I! are flexed and held between the chamfered edges.

Other means for picking up stamped-out fourchettes are shown in Figure 10 depicting a die I0a generally similar to that shown in Figures 1 to 4 except for the absence of chamfered edges and the provision, in place of chamfered edges, of pins 26 adapted to pierce and pick up the stamped-out fourchettes. Such pins may be disposed at the middle of the die, as shown, or at the tips of the fourchettes. In Figure 10, the cutting blades, the central bridging member and the handle are indicated, respectively, by the reference numerals Ila, I2a and HM.

As shown in Figures 2 to 4, ejection means for stamped-out fourchettes picked up by the die include two levers 20 of heavy stiff wire or the like bent around a pivot pin 2I set transversely in the blades I I between the central plate I2 and the tapering divergence of the blades. One arm of each of the levers 20 extends forwardly on each side of the central blade II under the plate I2 around the diamond-shaped middle of the central blade. The other two arms of the levers extend upwardly beyond the blades I I and are connected by a transverse plate 22 spaced from the blade II to form a handle. A flat spring 23 affixed cantilever-wise to the top of the plate I2 by a screw 24 extends between the levers 20 and the plate 22 past the fork of the central blade II. When the lever 23 is depressed to position shown in Figure 3 with broken lines to eject picked-up fourchettes, the spring 23 is likewise depressed from its normal position to a position also shown in broken lines. The depressed spring urges the lever back to its original position when the lever handle is released.

The die disclosed hereinabove will stamp out the quirked fourchette indicated generally in Figure 8 with the reference numeral 30 and shown in Figure 9 folded as in a glove. In Figure 6, the same fourchette is shown as assembled in the second and third fingers of a left glove, the back side of the trank being indicated with the reference numeral 3| and the seam with the reference numeral 32. As shown in Figure '7, a quirk 33 is fitted in the crotch between the two fingers, the quirk being shown on a greater scale in Figure 5.

Figure 11 illustrates a pair of mated right and left straight fourchettes 35 and 36 struck out contiguously by the die of Figure 10. The small apertures left by the pins 26 are indicated at 31. The fourchettes 35 and 36 have straight, long edges 38 and other long edges 39 that curve outwardly nearly at their middles to adapt the fourchettes for assemblage in a glove without quirks.

Figure 12 illustrates a pair of mated right and left straight darted fourchettes M] as struck out contiguously by a die of the present invention. The dart is slightly off center so that one side of fourchettes is longer than the others. A die for stamping out the fourchettes of Figure 12 would differ from the die of Figure 2 by including a completely straight central cutting blade, the outer blades being characterized by re-entrant angles nearly at their middles.

The darts M of the fourchettes take the form of a re-entrant angle whose point is spaced from the opposed longitudinal edge by the distance required for a seam indicated by the broken line 42.

The present invention is not confined to the above described illustrative examples, for the broad scope of the invention covers devices for stamping fourchettes combining in one tool dies for stamping simultaneously and contiguously a pair of mated right and left fourchettes. Such dies may be used in clicking machines. The invention also includes, in fourchette dies, chamfered inside edges, pins and other means for picking up stamped-out fourchettes, as well as means, such as levers, for ejecting accumulations of picked-up fourchuettes. The invention also comprises straight fourchettes, for use with quirks, characterized by a re-entrant angle in a longitudinal edge whose point is spaced from the opposed long edge by a distance greater than that required for a seam. It is therefore not the intention to limit the scope of the patent granted on this invention, otherwise than necessitated by the scope of the appended claims.

I claim as follows:

1. In a die for stamping fourchettes including spaced cutting blades, the improvement comprising cutting edges chamfered on the insides of said blades, to flex and retain fourchettes stamped by said die, and means for ejecting from said die fourchettes retained thereby including a lever pivoted intermediate said cutting blades and having one arm extending therebetween and another arm extending upwardly beyond said blades.

2. In a die for stamping fourchettes including spaced cutting blades, the improvement comprising cutting edges chamfered on the insides of said blades, to flex and retain fourchettes stamped by said die, and means for ejecting from said die fourchettes retained thereby including a lever pivoted intermediate said cutting blades and having one arm extending therebetween and another arm extending upwardly beyond said blades, and spring means resisting displacement of said lever.

3. A device for stamping fourchettes including three spaced integral cutting blades extending in the same general direction, and having cutting edges chamfered on the inside, to pick up stamped-out fourchettes therebetween, the outer two blades having ends deflected inwardly and the central blade having forked ends joined to the deflected ends of said outer blades to outline the tapering ends of mated right and left straight fourchettes, a middle portion of said central blade dividing and spreading to form a diamond-shaped figure outlining darts in said straight fourchettes, said device further comprising a flat member bridging middle portions of said blades, a handle on said flat member, a pin set transversely in said blades intermediate the terminal forks of said central blade and said flat member, a lever pivoted around said pin on each side of the central blade, said levers having each one arm extending under said flat member between said blades capable of ejecting stampedout, picked-up fourchettes when depressed and another arm extending upwardly beyond said blades, a transverse plate connecting the latter lever arm whereby the latter lever arm may be actuated manually to depress said first lever arm, and a cantilever spring afiixed to said fiat member and extending therefrom between said latter lever arms and the plate connecting the same above the blades, to the end portions of the blades, said spring resisting depression of said levers.
